More than 70,000 bras of all shapes and sizes were stretched out in Riverside Park, West End, as part of a fundraiser for the Cancer Council.

Organiser Caryn Gorrie says she was overwhelmed by the attention her campaign has received.

"It's incredible; I'm just blown away by the support."

Forty people who make up the 'Bra Army' helped lay out more than 30 rows of the donated bras in a one-kilometre stretch of path in West End on October 5.

Ms Gorrie organised the fundraising campaign to raise awareness of the Cancer Council and funds for their cancer vaccination research, and saw the record-breaking attempt as a great way of turning heads.

"It wasn't to be, the stars didn't align but we're definitely going to break the record when we get to do this in the new year!"

In the meantime, the Cancer Council has received a donation of around $20,000 from Ms Gorrie.

Size does matter

The show of support was not enough to break the official record.

Ms Gorrie says four trucks carrying thousands more pledged bras from across the country unfortunately didn't make it to Brisbane in time for the attempt.

"We [also] seemed to have lost 9,000 bras on a train between [Brisbane] and Charleville," she says, "so there's a one tonne wheat pack of bras that might turn up at some farm. I'm sure they'll have a laugh," Ms Gorrie says.

The current world record for the world's longest bra chain is held by a group of New Zealand Girl Guides who managed to collect 170,000 bras, measuring 170-kilometres long.

During the 2013 campaign to get donations of money and old bras for the record attempt, Ms Gorrie enlisted the help of ABC Local Radio's Spencer Howson.

Within a week of their first chat on air, boxes of bras were being delivered to the ABC headquarters in Brisbane with Spencer's name on them.

Donations of bras have come in from across Queensland, Tasmania, Victoria, and northern NSW.

Ms Gorrie says the bras that have been donated will be repurposed and delivered to people in need of the extra support.

Ms Gorrie is continuing to accept donations of money and bras until the end of 2013.
